    Bug Description: DS Console shows escaped DNs
    Reviewed by: nkinder (Thanks!)
    Branch: HEAD
    Fix Description: Was not working correctly in the property and advanced
    editor for editing some DNs that contained other DNs as RDN values.
    I also moved a lot of the DN handling code into the main console package
    into the LDAPUtil class.  This will allow the main console to handle DN
    escapes as well.  Unfortunately, if managing a new DS on a machine which
    only has the old console framework, these methods will be missing.
    So, use the new methods if available, otherwise, fallback on the DSUtil
    implementation.
